This was made much easier by introducing an IncludeCategory struct to
replace the previously used std::pair.

Also, cleaned up documentation and added examples.

control the individual braces. The existing choices for brace wrapping
are now merely presets for the different flags that get expanded upon
calling the reformat function.

All presets have been chose to keep the existing formatting, so there
shouldn't be any difference in formatting behavior.

Also change the dump_format_style.py to properly document the nested
structs that are used to keep these flags discoverable among all the
configuration flags.

Rename AST node matchers to match the AST node names directly. Part of this rename also splits recordDecl() (which used to match CXXRecordDecl) into recordDecl() (that matches RecordDecl) and cxxRecordDecl (that matches CXXRecordDecl). Also adds isStruct(), isUnion(), and isClass() narrowing matchers for RecordDecl objects.

Revise doc description of use-after-dtor.

Change wording to specify memory no longer readable.

Fixed HasDeclarationMatcher to properly convert all types into decls where possible. Added objcObjectPointerType(), objcInterfaceDecl(), templateTypeParmType(), injectedClassNameType(), and unresolvedUsingTypenameDecl(). Updated documentation for pointerType() to call out that it does not match ObjCObjectPointerType types. Changed pointsTo() to handle ObjCObjectPointerType as well as PointerType.

While this may seem like a lot of unrelated changes, they all relate back to fixing HasDeclarationMatcher.

This now allows us to write a matcher like:

varDecl(hasType(namedDecl(hasName("Foo"))))

that matches code using typedefs, objc interfaces, template type parameters, injected class names, or unresolved using typenames.

as runtime bitset checks at indirect call sites. Depends on the new function

This patch depends on r246688 (D12341).

The goal is to make LLVM generate different code for these functions for a target that
has cheap branches (see PR23827 for more details):

int foo();

int normal(int x, int y, int z) {
   if (x != 0 && y != 0) return foo();
   return 1;
}

int crazy(int x, int y) {
   if (__builtin_unpredictable(x != 0 && y != 0)) return foo();
   return 1;
}

to enable the use of external type references in the debug info
(a.k.a. module debugging).

The driver expands -gmodules to "-g -fmodule-format=obj -dwarf-ext-refs"
and passes that to cc1. All this does at the moment is set a flag
codegenopts.

This change adds the new unroll metadata "llvm.loop.unroll.enable" which directs
the optimizer to unroll a loop fully if the trip count is known at compile time, and
unroll partially if the trip count is not known at compile time. This differs from
"llvm.loop.unroll.full" which explicitly does not unroll a loop if the trip count is not
known at compile time

With this change "#pragma unroll" generates "llvm.loop.unroll.enable" rather than
"llvm.loop.unroll.full" metadata. This changes the semantics of "#pragma unroll" slightly
to mean "unroll aggressively (fully or partially)" rather than "unroll fully or not at all".

The motivating example for this change was some internal code with a loop marked
with "#pragma unroll" which only sometimes had a compile-time trip count depending
on template magic. When the trip count was a compile-time constant, everything works
as expected and the loop is fully unrolled. However, when the trip count was not a
compile-time constant the "#pragma unroll" explicitly disabled unrolling of the loop(!).
Removing "#pragma unroll" caused the loop to be unrolled partially which was desirable
from a performance perspective.

Summary:
Add brace style `BS_WebKit` as described on https://www.webkit.org/coding/coding-style.html:

* Function definitions: place each brace on its own line.
* Other braces: place the open brace on the line preceding the code block; place the close brace on its own line.

Set brace style used in `getWebKitStyle()` to the newly added `BS_WebKit`.
